X射线或中子衍射实验可以提供晶体材料的微观结构信息。在不明确材料具体的微观结构模型时,Warren-Averbach分析一直被视为非常重要的手段。为此,开发了一个Warren-Averbach分析程序,该程序包含对衍射数据进行Warren-Averbach分析的基本功能,并可通过用户图形界面方便地使用。最后,以二氧化铈为例,使用该程序对它的中子粉末衍射数据进行了分析。 X-ray or neutron diffraction experiments can provide microstructural information on crystalline materials. The Warren-Averbach analysis has always been regarded as a very important tool when it is not clear about the material-specific microstructure model. To this end, a Warren-Averbach analysis program has been developed that includes the basic functionality of Warren-Averbach analysis of diffraction data and is conveniently available through the user's graphical interface. Finally, ceria is used as an example to analyze its neutron powder diffraction data using this program.
